Background: Therapeutic plasma exchange has been tried as a treatment approach for systemic sclerosis since 1978 based on the rationale that some circulating factor is involved in disease pathogenesis, for example, autoantibodies or immune complexes, and that removing the potential pathogenic factors could lead to symptom improvement. Based on our impression that clinicians and researchers are largely unaware that a large volume of research has been published about the use of therapeutic plasma exchange as a treatment for systemic sclerosis, we conducted a comprehensive review and analysis of all published research on this topic.
Results: We identified 46 relevant articles that met our search criteria, involving a total of 572 patients. Of these, 19 were case studies; the rest ranged from small observational studies to prospective randomized clinical trials. In all but two studies, most patients receiving therapeutic plasma exchange showed improvements in both clinical symptoms and laboratory markers, including significant improvement in Raynaud's symptoms and healing of digital ulceration after three to four weekly treatments. The beneficial effects from even a short course of therapeutic plasma exchange treatments were long-lasting, typically 6 months or longer. Therapeutic plasma exchange was very well tolerated. Adverse events were rare and, in almost all cases, mild and transitory.
Conclusion: These results suggest that long-term therapeutic plasma exchange may offer a low-risk way to control and in some cases reverse systemic sclerosis symptoms. The mechanism for the clinical improvements seen from therapeutic plasma exchange in systemic sclerosis patients is unclear. Therefore, additional studies of therapeutic plasma exchange effects in systemic sclerosis appear to be highly desirable.

Background: Systemic lupus erythematosus (SLE) is a complex and incurable autoimmune disease, so several drug remission for SLE symptoms have been developed and used at present. However, treatment varies by patient and disease activity, and existing medications for SLE were far from satisfactory. Novel drug targets to be found for SLE therapy are still needed.

Liver-expressed antimicrobial peptide 2 (LEAP2) has recently emerged as a novel hormone that reduces food intake and glycemia by acting through the growth hormone secretagogue receptor (GHSR), also known as the ghrelin receptor. This discovery has led to a fundamental reconceptualization of GHSR's functional dynamics, now understood to be under a dual and opposing regulation. LEAP2 exhibits several distinctive features.

Introduction: Neuromyelitis optica (NMO) is an idiopathic demyelinating disorder characterized mainly by optic neuritis and myelitis, causing gradual loss of vision and deterioration of neurological function. The underlying pathogenesis mainly involves antibodies against aquaporin 4. The effectiveness of therapeutic plasma exchange (TPE) has been shown by many studies across the globe but are only a few from India.

Introduction: Platelet transfusion has been therapeutically used in patients with thrombocytopenia and platelet function defects over the years. The use of advanced techniques may add value in assessing the quality of platelet products. The aim of the study was to assess stored platelet concentrates (PCs) prepared in blood banks for platelet indices, clot strength, and platelet function.

We describe a previously uncharacterized ATP-binding cassette A1 super enhancer RNA (ABCA1-seRNA)-mediated cholesterol efflux. In addition, it promoted macrophage inflammatory cytokine release, and was causally correlated with coronary artery disease severity. Mechanistically, ABCA1-seRNA upregulated cholesterol efflux by interacting with mediator complex subunit 23 and recruiting retinoid X receptor-alpha and liver X receptor-alpha to promote ABCA1 transcription in a manner.
